Várices esofágicas sangrantes - Información general

Definición:

Se presentan cuando las venas en las paredes de la parte inferior del esófago y, algunas veces, la parte superior del estómago están más anchas (dilatadas) de lo normal.

Causas, incidencia y factores de riesgo:

Las várices sangrantes son una complicación potencialmente mortal del aumento de la presión sanguínea en la vena porta causada por enfermedad hepática (hipertensión portal). La vena porta lleva sangre desde el intestino al hígado.

El aumento de presión hace que las venas se inflen hacia afuera y los vasos pueden romperse. Cualquier causa de enfermedad hepática crónica puede ocasionar várices sangrantes.
